Visualization of spin-orbit entangled 4f electrons in crystalline materials
Shunsuke Kitou, Kentaro Ueda, Yuiga Nakamura +5
Lanthanide 4f electrons are strongly influenced by spin-orbit coupling, resulting in well-defined J multiplets, which are further split by the crystalline electric field in condens…
